Description: Resistors are a good thing, in fact, they're actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you're gonna have the resistor you need when you need it is to stock up, and keep them organized. We have just the thing!

Our new branded resistor kit comes with 25 each of 20 different resistor values (including 0Ω links!). All of these resistors are stapled into a tri-fold pack and clearly labeled. The back of the resistor kit even has a resistor color code look-up chart and a table of color codes for the included resistors!

We'd like to give Oomlout credit for coming up with this great idea. Thanks guys!

Values Included:

  • 0Ω, 1.5Ω, 4.7Ω, 10Ω, 47Ω
  • 100Ω, 220Ω, 330Ω, 470Ω, 680Ω
  • 1kΩ, 2.2kΩ, 3.3kΩ, 4.7kΩ, 10kΩ
  • 22kΩ, 47kΩ, 100kΩ, 330kΩ, 1MΩ

Replaces: COM-09258

  • I want this, but with capacitors. Please?

    • Double ditto! I just bought the assorted ceramic capacitor bag from RipoffShack, and out of the 100 in the bag, there was not a single one I could use in my project. Plenty of 10pF caps, though.

    • Ditto on the caps!

    • yes, though ceramic or film caps that would be used in exact values in filters, not electrolytics

  • This is long overdue, but very nicely executed. Kudos.

  • How stiff are the wires on the resistors? I have bought an assortment in the past that had thin wires that were hard to insert into a breadboard without them bending up.

    • In my experience, ¼ watt resistors tend to have leads similar to 22 AWG wire.

      • I have some ¼ watt with a wire thickness of 0.021" and others with a wire thickness of 0.017. One size goes into a breadboard nicely the others don’t

        • Hi,

          I bought this kit a while back. To answer your question, they are not extremely stiff. For direct PCB/proto board soldering, it is good. For breadboard, I find them too maleable for the task. However, my breadboard is really stiff.

  • Quite a nice kit, but I believe the 110R resistor is actually 100 ohms… its actually printed as 110 on the front cover but 100 inside the cover.

  • mentioned the 0 Ohm resistors to my brother in law (masters in EE) says they use them in circuit design on PCBs just in case your calculations are wrong and a specific area might need more resistance. Still I think whats wrong with a wire instead but hey I don’t have a masters in Electrical Engineering.

    • “A zero-ohm link or zero-ohm resistor is a wire link used to connect traces on a printed circuit board that is packaged in the same format as a resistor. This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire. Zero-ohm resistors may be packaged like cylindrical resistors, or like surface-mount resistors.”

      from wikipedia… used so that they dont need a different machine for jumpers.

      • Yeah I’ve been thinking about this for a while and having 0 Ohm resistors at your disposal would make PCB design easier. Especially for the layperson whom can probably only manage a 2 sided PCB.

    • it’s identical to a wire, but with the same body as a resistor so it can be grabbed by a machine. there’s no reason to include them in this kit meant for hobbyists. just use a wire.

  • 0 ohm resistors? I’ve got spools of those and they’ve even got insulation on the outside.

  • It would be awesome to get one of these full of ceramic caps!

  • When will they be back in stock?

  • “25 each”? Should be a lot more 10 kΩ and 100 kΩ than other values, since you use those a lot more.

  • Thanks did not see that.

  • When will it be back in stock.

    • For products that are out of stock, SFE tries to give an estimate for new stock on the right hand side of the product page. Currently (2014/01/24) it reads: “We have a purchase for 2000 units. We expect some of these to arrive next on Feb 2, 2014.” I do stress that this is an estimate, however, as logistical issues can always rear their head.

  • What is the pin spacing on these? 100mil, 200mil,300mil,400mil? this is for designing PCBs and need the correct pin spacing for these….Thanks.

  • An irresistible addition to anyone starting out in electronics.

    Color codes in ACTUAL color is a nice touch! I will eventually cut that out and save it when I move my small components and datasheets to a binder (baseball card storer + small baggies).

    I tried putting these resistors in my stiffest breadboard and had with no problem at all! My loosest breadboard holds them pretty good as well.

  • Can we have a PDF of the chart on the back? The sticker is great, but the color version is much more effective.

  • can we get the old unbranded kit back? this kit is way short on values! Also do we really need to pay for 0Ω resistors as part of the kit? I’d call that wire! (unless by some stretch of physics you have found a way for these to really be 0Ω±5% then maybe you could auction them along with your nobel prize!)

  • Is there an SMD version?

  • If only it had some median resistor sizes… Never know when you will need a 12 ohm resistor… Awesome set of resistors for LED noobs to play with…

  • Is there any diference between 1/4W and 1/6th Watt PTH at Resistor 330 Ohm 1/6th Watt PTH.

  • I love it!

  • any idea when this is coming back in stock?

    • I have an order with this backordered and was told they’ll have it in stock in the “[n]ext couple of weeks”.

  • Might wanna add “carbon film” and their tolerance to the description, so we don’t have to squint at the picture. ;)

  • Been waiting for something like this! Picked one up.

  • Are these all 5%?

    • Apart from the 0 Ohm resistors, yes. If you look closely at the packaging, you can see the +- 5%. The 0 Ohm resistors are of course +- Infinite % :-)

  • Zero ohm resistors? really? Okay, I can see a use, but I’d really just use a piece of wire, rather than pay for a resistor.

    • Wire looks shoddy. When I open something up from china and see wire jumpers, I am immediately disappointed. But 0Ω resistors look good!

      • I just busted open my old alarm clock and there was wire jumpers all over the place. I have to admit, I was rather disappointed. However I did salvage all kinds of neat parts. I am definitely picking up one of these sweet kits.

        • This kit is on its way to my house along with an Arduino Uno R3 and various other sweet parts. Can’t wait for it to arrive.

  • great stocking stuffer.

    Papa Smurf does bring up a good point. Why 0 ohm? Why not use a piece of wire?

    • Although not really relevant here, they are useful in pick and place, where a wire bridge won’t work properly.

  • Wow really, a Zero ohm resistor?!?! Sometimes I wonder about U guy’s (sniffin too much leaded soldor)

    • I am going to build the world’s highest-precision R2R ladder out of several reels of those 0Ω resistors, once I can find some that are exactly twice their value.

    • They actually are pretty common. They are used in pick and place machines as jumpers- I think wire bridges are harder/require more specialized equipment… :)

    • Actually lead-free solder is much worse for you.

    • The only point I can see in these things is that those who are embarrassed about using jumpers can now make connections without tarnishing their project.

      0 Ohm. Really??

      • 0 Ohm resistors are very commonly used in professional engineering design. They typically have two purposes - 1) you can change the resistor value later if desired. Or, 2) you can use the location as a machine-populated jumper. Then you can save money manufacturing PCBs by designing a board that does several different things, but some features are only enabled if the assembly specifies including that ‘resistor’.

      • We manufacture thousands and thousands of PCB’s where I work, for alot of large international customers and we use 0 ohm resistors and almost every board that we use. They are very common components actually.

      • It’s linked in the product description; http://en.wikipedia.org/wiki/Zero-ohm_link

        “This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire.”
